The boundary layer thickness is usually defined as the distance from the wall to the point where the flow velocity reaches 99 % of the free stream value.
In the very thin boundary layer associated with free stream flows with high Reynolds numbers, a steep rise in velocity occurs perpendicular to the wall.
Boundary layer thickness = 0.37*Distance on x-axis/(Reynolds Number^(1/5))
δ = 0.37*x/(Re^(1/5))
This formula uses 3 Variables:
Variables Used
Boundary layer thickness - (Measured in Meter) - Boundary layer thickness is the distance normal to the wall to a point where the flow velocity has essentially reached the 'asymptotic' velocity.
Distance on x-axis - (Measured in Meter) - Distance on x-axis is the distance of point measured along x-axis form origin.
Reynolds Number - The Reynolds number is the ratio of inertial forces to viscous forces within a fluid which is subjected to relative internal movement due to different fluid velocities. A region where these forces change behavior is known as a boundary layer, such as the bounding surface in the interior of a pipe.

A patriarchal society is a society where the power is in the hands of men, and is not distributed between men and women and it's not in the hands of the men.
So the answer is that in classical China all the political, social and economic power was in the hands of men. <span>

Answer:D WWII has a greater impact on the United States than WWI did.
Explanation: the higher number would have impacted the United States much more
They needed people to work the factories with the men are gone to war.
